Abstract
Description
Technical Field
[0001] This invention relates to the field of walking aids, and in particular to an intelligent walking aid. Background Technology
[0002] Patients with injuries, disabilities, or the elderly often have mobility issues. Rehabilitation assistive devices such as walking aids can help these users walk, achieve certain rehabilitation training goals, and enable users to take care of themselves in rehabilitation treatment or mobility, bringing convenience to the users and their families.
[0003] Currently, when users need to rest, walking aids mostly only allow them to stand still, which is not conducive to leg relaxation. When physical strength is insufficient, the hand support is inadequate, causing the user's body to tilt. The bottom of the walking aid is mostly rectangular, with a fixed force-bearing area. When the user's center of gravity is outside the bottom of the walking aid, the user is prone to falling. Walking aids mainly serve a supporting function. When physical strength is no longer sufficient to continue walking, the user cannot return home. At the same time, if the user experiences incontinence outdoors, frame-type walking aids lack shelter, which can easily damage the user's self-esteem. Summary of the Invention
[0004] The purpose of this invention is to provide an intelligent walking aid. When the user needs to rest or is too tired to hold on, the electric push rod will push the seat plate upward to rotate, making it easier for the user to sit down and rest. The drive vehicle can take the user back to their residence. The elastic band is elastic and provides a certain cushioning effect, which can prevent the user from falling when they are too tired. The support rod increases the support area and makes it more stable. When the user experiences incontinence, the toggle block can be activated to cover the side frame of the vehicle, thereby protecting the user's self-esteem.

[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] 1. This invention, by setting up a restraint strap, an electric push rod, and a seat, allows the user to move downwards when they need to rest or become exhausted and lose their grip. This pulls the restraint strap and elastic band downwards, causing the moving block to slide. The first spring is compressed, and when the moving block contacts the push switch, the electric push rod is activated, extending and pushing the seat to rotate upwards, making it easier for the user to sit down and rest. At the same time, the restraint strap provides a certain pulling force, and the elastic band provides a certain cushioning effect, preventing the user from falling when exhausted.
[0024] 2. This invention, by setting up a support rod and a pedal, allows the pull rod to move upwards when the seat is supported, thereby pulling the second rack upwards. Through the gear, the first rack moves downwards, pushing the support rod downwards. The second spring is compressed, and the support rod slides along the fixed column through the inclined groove, thereby causing the support rod to extend outwards. The universal wheel at the bottom of the support rod will contact the ground, thus providing a certain degree of support and preventing the vehicle from tilting backwards when the user is seated, thus making it more stable. During the outward extension of the support rod, the telescopic rod is pulled, thereby pulling the pedal out, which facilitates the placement of the user's feet. The vehicle can be driven by remote control.
[0025] 3. This invention, by setting up a toggle block, a shielding plate, an air duct, and a closing plate, allows the user to extend the shielding plate inside the cavity when incontinence occurs. This shielding plate covers the side frame of the vehicle body, protecting the user's self-esteem. After the toggle block is activated, it disengages from the sliding rod, and the fourth spring extends, pulling the push plate and sliding rod towards the toggle block. One end of the push plate contacts the inclined end of the closing plate, thus opening the closing plate. The torsion spring is compressed, allowing external air to enter the interior of the vehicle body through the air duct, achieving air circulation and preventing odors from causing discomfort to the user.

A second spring 44 is fixedly connected between the bottom of the first rack 45 and the vehicle body 1. The second spring 44 acts as a pusher, pushing the first rack 45 to move upward, thereby causing the second rack 47 to move downward. This causes the pull rod 48 to pull the seat plate 35 to fit against the vehicle body 1, thus facilitating the user's movement and avoiding space occupation.
[0045] A pedal mechanism 7 is connected to the vehicle body 1. The pedal mechanism 7 includes a pedal 71, a telescopic rod 72, and a fixed cylinder 73. The pedal 71 is slidably connected to the bottom of the vehicle body 1. One end of the pedal 71 is rotatably connected to the fixed cylinder 73.

One end of the telescopic rod 72 is rotatably connected to the support rod 41 on the same side, which facilitates the placement of the user's feet. The third spring 74 can prevent the pedal 71 from hitting the user's legs, thus playing a certain cushioning role. At the same time, the pedal 71 can be wrapped with sponge for greater safety.
[0046] The pedal 71 has a “]” shaped structure and is located at one end near the drive vehicle 2, so that the pedal 71 can be extended.
[0047] according to Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the vehicle body 1 has a frame-like structure, and a shielding mechanism 8 is connected to the vehicle body 1. The shielding mechanism 8 includes shielding plates 81. Multiple shielding plates 81 are slidably connected inside the side wall of the vehicle body 1. The multiple shielding plates 81 are rotatably connected to each other. A toggle block 82 is slidably connected to the top of the side wall of the vehicle body 1. The bottom end of the toggle block 82 is fixedly connected to the top end of a shielding plate 81 near the outside of the vehicle body 1. A cavity for storing the shielding plate 81 is provided inside the side wall of the vehicle body 1. The shielding plate 81 is made of a tough plastic material, so that the shielding plate 81 can stand up.
[0048] An iron block 83 is fixedly connected to the top of the shielding plate 81. The iron block 83 is slidably connected to the vehicle body 1. A magnetic block 84 is fixedly connected to the top of the vehicle body 1 in the cavity. The iron block 83 is used to attract the magnetic block 84 to prevent the shielding plate 81 from moving randomly.
[0049] A wind guide mechanism 9 is connected to the vehicle body 1. The wind guide mechanism 9 includes a wind duct 91 and a closing plate 92. The side wall of the vehicle body 1 is provided with a wind duct 91. The vehicle body 1 is rotatably connected to the closing plate 92 on one side of the wind duct 91. A torsion spring 97 is installed between the closing plate 92 and the vehicle body 1. A slide rod 94 is slidably connected to the top side of the vehicle body 1 at the top of the wind duct 91. One end of the slide rod 94 is used to abut against the toggle block 82. A push plate 99 is fixedly connected to the end of the slide rod 94 that extends into the wind duct 91. A fourth spring 95 is fixedly connected between the push plate 99 and the vehicle body 1. The cross-section of the closing plate 92 is triangular. One end of the push plate 99 abuts against the inclined surface of the closing plate 92. A limiting component for limiting is connected to the toggle block 82.
[0050] The push plate 99 is rectangular and made of elastic material, so as to prevent the push plate 99 from being damaged when the closing plate 92 is impacted.
[0051] The limiting component includes an abutment block 98. The bottom end of the toggle block 82 is slidably connected to the abutment block 98. A fifth spring 96 is fixedly connected between the abutment block 98 and the toggle block 82. The vehicle body 1 is provided with multiple arc-shaped abutment grooves 93. The bottom end of the abutment block 98 has an arc-shaped structure. The bottom end of the abutment block 98 extends into the interior of the abutment groove 93 and abuts against the vehicle body 1, thereby limiting the free sliding of the toggle block 82.
[0052] In practical use: This invention is an intelligent walking aid. During rehabilitation training, users with leg disabilities can enter the vehicle body 1 by opening the closed door 6. When not in use, the seat 35 is in an upright position. The restraint strap 31 is tightened around the user's waist. Moving the knob 32 adjusts the position of the slider 34 to accommodate the user's height. After adjustment, tightening the knob 32 locks the slider 34 in place. The user can then walk while holding onto the vehicle body 1. The vehicle body 1 will drive the drive unit 2 and the casters 5 to rotate and move. When the user needs to rest or becomes exhausted and loses their grip, their body will move downwards, pulling the restraint strap 31 and elastic band 37 downwards. This causes the moving block 33 to slide, compressing the first spring 38. When the moving block 33 contacts the push switch 39, the electric push rod 36 will extend, pushing the seat plate 35 upwards, making it easier for the user to sit down and rest. Simultaneously, the restraint strap 31 provides a pulling force, and the elastic band 37, being elastic, provides cushioning, preventing the user from becoming too tired. When a person falls and stands up after resting, the restraint strap 31 moves upward, and the first spring 38 pushes the moving block 33 to slide, thus disengaging it from the push switch 39. The electric push rod 36 retracts automatically, causing the seat plate 35 to return to its original position, avoiding space occupation. As the seat plate 35 is supported, it pulls the pulling rod 48 upward, thereby pulling the second rack 47 upward. Through the gear 46, the first rack 45 moves downward, pushing the support rod 41 downward. The second spring 44 is compressed, and the support rod 41 slides through the inclined groove. 42 slides along the fixed column 43, thereby causing the support rod 41 to extend outward. The universal wheel 5 at the bottom of the support rod 41 will contact the ground, thereby providing a certain support and preventing the vehicle body 1 from tilting backward when the user is sitting, thus making it more stable. When the user is unable to walk, the user sits down, and the support rod 41 will pull the telescopic rod 72 as it extends outward. The third spring 74 will be stretched, causing the fixed cylinder 73 to move, thereby pulling the pedal 71 outward, thus facilitating the placement of the user's feet. The vehicle 2 can be driven to move by remote control.When a user experiences incontinence, the actuating block 82 can be activated, causing the shielding plate 81 inside the cavity to extend. An iron block 83 is fixedly connected to the top of the shielding plate 81, and the iron block 83 attracts the magnetic block 84, effectively preventing the shielding plate 81 from sliding freely. The actuating block 82 causes the shielding plate 81 to extend, thus shielding the side frame of the vehicle body 1 and protecting the user's self-esteem. The fifth spring 96 on the actuating block 82 pushes the bottom end of the abutment block 98 into the abutment groove 93, thus providing a certain limiting effect. After the actuating block 82 is activated, it will engage with the sliding rod 9... 4. When disengaged, the fourth spring 95 extends, pulling the push plate 99 and slide rod 94 towards the actuating block 82. One end of the push plate 99 abuts against the inclined end of the closing plate 92, thereby pushing the closing plate 92 open. The torsion spring 97 is compressed, allowing external air to enter the interior of the vehicle body 1 through the air duct 91, thus achieving air circulation. When the actuating block 82 is moved to open the cover plate 81, the actuating block 82 pushes the slide rod 94, causing the push plate 99 to disengage from the closing plate 92. Under the action of the torsion spring 97, the closing plate 92 closes, facilitating the next operation.
[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
